• Develop and enhance UE and base station emulation
• Contribute to pre‑6G standards, following 3GPP evolution
• Translate evolving requirements (3GPP releases, operator acceptance needs, O‑RAN priorities) into clear software designs, test workflows, and reusable components
• Collaborate with cross‑functional experts (systems, RF, protocol, product, customers/partners) to reproduce field issues, debug complex behaviors, and deliver fixes with strong root‑cause discipline

Qualifications

• Expertise in 3GPP LTE / NR
• Focus on L1 protocols and Scheduler alogorithms
• C / C++
• Real‑time programming
• Software development and debugging
• Technical communication in English
